Is impulse delivered to an object equal to a change in the objects velocity?
Yes, impulse is equal to the change in momentum of an object, which can be calculated as the mass of the object multiplied by the change in velocity. So, impulse is related to the change in velocity of an object.
If the velocity is constant does that mean that the impulse is the momentum?
No, constant velocity means there is no change in velocity over time. Impulse is the change in momentum, given by the force applied over a period of time. Momentum is mass times velocity, a vector quantity.
If the velocity is constant does that mean that there is no impulse?
Not necessarily. Impulse Fdt=change in momentum which could be written as mdv (constant mass, velocity changing) or dmv (changing mass, constant velocity - the so-called conveyor belt problem. Imagine a hopper filled with (say) coal is feeding the coal on to a conveyor belt. The mass of the belt increases with time, so a force has to be applied to it to keep it moving at constant velocity.
How much in the impulse increase if an object is doubled?
If the mass of an object is doubled, its impulse will also double if the change in velocity remains the same. Impulse is equal to the change in momentum, so if both mass and velocity double, the impulse will quadruple.
What is dimension of impulse?
The dimension of impulse is equivalent to the dimension of momentum, which is mass multiplied by velocity, or kg*m/s.
How can you find the value of the impulse?
The value of an impulse is the change in momentum. If the mass remains constant it is the mass times the change in velocity.
Is impulse delivered to an object equal to a change in the objects velocity?
Yes, impulse is equal to the change in momentum of an object, which can be calculated as the mass of the object multiplied by the change in velocity. So, impulse is related to the change in velocity of an object.
How can impulse increase?
Impulse is denoted as a change in momentum. Momentum has the units of kilogram meter per second. Which is mass times velocity. So you can decrease the time and increase the velocity to increase the impulse.
If the velocity is constant does that mean that the impulse is the momentum?
No, constant velocity means there is no change in velocity over time. Impulse is the change in momentum, given by the force applied over a period of time. Momentum is mass times velocity, a vector quantity.

How can find impulse with mass and velocity given?
Impluse = m x v
How much in the impulse increase if an object is doubled?
If the mass of an object is doubled, its impulse will also double if the change in velocity remains the same. Impulse is equal to the change in momentum, so if both mass and velocity double, the impulse will quadruple.
How is impulse relative to momentum?
impulse (force x time) is equal to momentum (mass x velocity); Ft=mv
How do you impulse?
The impulse of force is commonly used to calculate forces in collisions. Active formula. Impulse = Average force x time = mass x change in velocity
How can impulse be increase?
Impulse is denoted as a change in momentum. Momentum has the units of kilogram meter per second. Which is mass times velocity. So you can decrease the time and increase the velocity to increase the impulse.
What is dimension of impulse?
The dimension of impulse is equivalent to the dimension of momentum, which is mass multiplied by velocity, or kg*m/s.
A ball with a mass M is falling on to the ground with some velocity V1 and raising with velocity V2 find the impulse?
Impulse = |change in momentum| Initial momentum = MV1 down Final momentum = MV2 up Missing momentum = impulse = M ( V1 - V2 )
